How Firebase Auth Pricing Works
Firebase Auth uses a freemium model: a free plan with limited features and paid plans that unlock the full toolkit. In practice, Firebase Auth bills based on the plan you choose, so your total cost scales with how the team uses it.
Is Firebase Auth Free?
Yes — Firebase Auth offers a free (freemium) plan, so you can try it without a credit card. Free plans typically limit users, storage volume, or advanced features.
- Always check the trial length and whether a credit card is required.
- Compare free-plan limits with your team's real needs.
- Visit Firebase Auth's official website for the latest price list.
